Pago Pago Harbor

Pago Pago Harbor (pronounced Pango Pango) is one of the world's largest, deepest, and most dramatic natural deep-water harbors, located on the island of Tutuila in American Samoa. Formed within the collapsed caldera of an ancient volcano, this fjord-like bay stretches over two miles inland with depths exceeding 400 feet, making it exceptionally sheltered by surrounding mountain ridges.
